In the East End of London, Shoreditch has become popular in the last number of years with high earners from Canary Wharf and the City, bringing with them a desire for the quirky and often high-end prices.

The unusual eatery was opened at the end of last year by twin brothers Alan and Gary Keery.

They said that customers - including children - were in the building at the time a mob, they said was 200 strong, rushed the building, throwing 'paint and fire'.

The businesses' Twitter account read: "Tonight we were attacked with paint and fire by an angry mob of 200. Riot police are on the scene.

"Staff and customers unharmed, although children were in the cafe, mob still around so stay away from Shoreditch."

A tweet from the account also read: "We started a business to deliver an experience to cereal lovers, and have been thanked by local businesses for bringing tourists to the area."

It opened today, Sunday, as normal.

The Guardian reported that Scotland Yard had said it arrested one person in relation to the incident.

In a statement, the Met said: “On Saturday 26 September, police officers dealt with disorder arising from a pre-planned event in the Shoreditch area.

“From around 8pm, a criminal element within a group of several hundred people threw missiles and caused criminal damage to shops and other businesses in and around Brick Lane, E2. The group continued to move around the Shoreditch and Brick Lane area until around 12.30am on Sunday 27 September.

“One officer suffered a minor injury to his face as a result of a bottle thrown. One person has been arrested on suspicion of criminal damage.”
